The “Atmosphere” Model: Analysis of the Time Series of Updates to the Deformations of the Earth Surface

详细

RT-22 radio telescope in Katsiveli (“Simeiz” VLBI station) is used extensively in international projects aimed at supporting spacetime reference systems for monitoring global changes on the Earth and for precise navigation in space. This paper discusses the results of the analysis of the data about the variations of the updates to the deformations of the Earth surface at Katsiveli site computed in terms of the “Atmosphere” model of a DFG (Deutsche Forschungsgemeinschaft) project. Significant oscillation with a one-year period is found in the Eastern and vertical components of the update vector to the deformations of the Earth surface at Katsiveli sit and the parameters of the sine model of this oscillation are computed.
